CUTTING ATTACHMENT FOR LOOIVIS.

Specification of Letters Patent.

Patented April 23, 1907.

Application filed September 22, 1906. Serial No. 335,674.

T0 all whom 7225 may concern.-

Be it known that I, ALBERT TILT, a citizen of the United States,residing in Montclair, Essex county, State of New Jersey, have inventedcertain new and useful Improvements in Cutting Attachments for Looms;and I do hereby declare the following to be a full, clear, and exactdescription of the inven tion, such as will enable others skilled in theart to which it appcrtains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

My invention relates to looms for weaving plural-width fabrics, and ithas reference particularly to the mechanism, commonly associated withsuch looms, for cutting or dividing the fabric into the respectiveportions thereof.

My invention comprehends the use of a movable blade, and itdistinguishes from previous devices having movable blades in that theblade moves in substantially the direction in which its edge extends andat an angle to the plane of the goods, which feature I find is of greatvalue in insuring a straight, true cut and the avoiding, thus, of damageto the inside selvages oi the goods. It should be understood, however,that my in vention is not limited to this feature in its every aspect,as certain other features thereof are new in themselves, to the best ofmy present knowledge.

I have illustrated my invention in full in the accompanying drawings,wherein,

Figure 1 shows it applied to a loom, the whole being shown in sideelevation; Fig. 2 is a top plan view of what is seen in Fig. 1; Fig. 3is a perspective view; and, Fig. 4 is a sectional view on line 30-01; inFig. 3. I

In. said drawings, the loom frame a, cloth roller 3), sand-roller c,breast-beam (Z, metal breast roller (2, batten f, lay-swords g,rockshaft h, shuttle i, reed j and harness j are or may be constructedandarranged substanti ally as in ordinary looms.

On the breast-beam and at suitable intervals, for instance, at both endsthereof, are placed brackets 7c in which are j ournaled the trunnions orreduced end portions Z oi a shaft m. This shalt-carries two arms aprojecting toward the front of the loom, horizontally, and having theirfree ends upturned, as at 0. G11 the upturned ends of said arms ismounted a rod p having holes Q to receive said ends of the arms. Thisrod forms a sup port for the cutters shown in Figs. 3 and 41-, each ofwhich consists of a blade 1' having a sleeve 3 penetrating the same inits upper portion and at right angles thereto. As many of these cuttersas are needed, according to the number 01 sections, of goods to bewoven, are mounted on the rod 2), which may be removed irom the arms ato permit the sleeves s to he slipped over it.

The relative form and arrangement of the brackets, shaft m, rod j), thecutters and the roller c are such that the cutters hang with theircutting edges 15 substantially vertical and their opposite ed in thelower portion thereof against the roller c, which roller resists thetendency oi the cuttters to turn on the rod p under the pull of thecloth. The blades 7' should be made somewhat wide, as shown, so that abroad bearing surhice will be presented to the already-cut edges of thegoods and thereby insure a straight cut.

On the rock shaft is arranged an arm a which is connected by a pitinan iwith a bent crank w secured to the rook-shaft m.

I11 the operation of the loom, as the goods advances and is drawnagainst the blades 7*, which are held from receding by the roller 0 asabove described, said blades move vertically, i. 6., substantially inthe direction in which the edge f of the blade extends, and since thisis at an angle to the plane of the goods, the blades cut the goodsevenly, avoid ing the wavy out which has been observed in the use ofprevious devices of this kind and which often results in damaging theselvage. The cutters being, as shown, arranged so as to slide laterallyon the rod 9, I am enabled to very conveniently set each at the precisepoint at which it is needed.

Having thus l'ull y described my invention, what I claim as new anddesire to secure by Letters Patent is:

1. In a loom, the combination, with the frame, of means for controllingthe warp and weft in the weaving operation a cutter having its cuttingedge disposed at an angle to the cloth plane, and means for moving thecutter in substantially the direction in which its cutting edge extends,substantially as described.

2. In a loom, the combination, with the frame, of means for controllingthe warp and welt in the weaving operation, a cutter havits cutting edgesubstantially straight and disposed at an angle to the cloth plane, and

IIO

tially the direction in which its cutting edge extends, substantially asdescribed.

4. In a loom, the combination, with the frame, of means for controllingthe warp and Weft in the weaving operation, a cutter, a

going part, a rocking structure carrying said cutter, and means foroperatively connecting said structure with the going part, substanltially as described.

5. In a loom, the combination, with the frame, of means for controllingthe warp and lweft in the weaving operation, a rocklng structurecomprising a substantial horizontal rod, a cutter pivoted on said rodand depending therefrom through the cloth plane, means for holding thecutter against pivotal movement on said rod under the pull of the cloth,and means for rocking said structure, substantially as described.

In testimony, that I claim the foregoing, I

have hereunto set my hand this 14th day of 0 September, 1906.

ALBERT TILT.
